The alkylgalactoside uronate is based on formula (I): ##STR1## R 1  is a C 8  -C 22  alkyl; R is (i) CH--CH(OH)--CO 2  R 2  or (ii) --CH(OH)--CH--CO 2  R 2 , 
     with the carbon carrying the hydroxyl group being linked to the endocyclic oxygen atom;

This applications claims priority under 35 USC 371 to PCT/FR 94/00642filed Jun. 1, 1994.

The invention relates to cosmetic compositions containing at least oneanionic surfactant of alkylgalactoside uronate type and at least onecationic polymer and to the use thereof in the treatment and washing ofkeratinous substances.

Compositions for washing the hair or the skin are generally formulatedfrom anionic or nonionic surfactants or their mixtures, optionally inthe presence of amphoteric surfactants.

Hair attacked by atmospheric agents such as light or chemical treatmentsand washed with conventional washing compositions is difficult todisentangle and this disadvantage is found to be further accentuated inthe case of wet hair.

It has been proposed to add cationic polymers to such washing bases inorder to improve the disentangling properties but the volume and theamount of the lathers, in particular their softness and theircompactness, are not satisfactory.

Anionic surfactants of alkylgalactoside uronate type have already beenrecommended in washing compositions for the hair. They have beendescribed in Patent Application EP-A-0,532,370.

Compositions for washing the hair which use these anionic or nonionicsurfactants alone do not lead to good cosmetic properties; inparticular, the disentangling of wet hair is difficult.

The Applicant Company has just surprisingly discovered that thecombination, in washing and/or treating compositions for keratinoussubstances, of an anionic surfactant of alkylgalactoside uronate typeand of a cationic polymer confer greatly improved disentanglingproperties, in particular for wet hair, on these compositions.

Moreover, the combination in accordance with the present invention makesit possible to obtain a copious, compact and very soft lather.

In addition, the Applicant Company has observed that the cosmeticcompositions containing such a combination confer good cosmeticproperties, such as softness and a pleasant feel, on keratinoussubstances.

The subject of the present invention is therefore cosmetic compositionscontaining at least one anionic surfactant of alkylgalactoside uronatetype and at least one cationic polymer, with the exception of cationiccellulose ethers.

Another subject of the invention consists of the use of thesecompositions for treating and/or washing keratinous substances such asthe hair or the skin.

Another subject relates to cosmetic treatment processes for the hair orfor the skin by means of the compositions of the invention; washing andtreatment processes for the hair being preferred.

The cosmetic compositions according to the invention contain, in acosmetically acceptable aqueous medium, at least one alkylgalactosideuronate and at least one cationic polymer, with the exception ofcationic celluloses such as cationic cellulose ethers or quaternizedcelluloses.
